Abstract

In this study, we formed the 2-dimensional holographic grating in order to mamufactured 2-dimensional photonic crystal in amorphous $As_{40}Ge_{10}Se_{15}S_{35}$ and $Ag/As_{40}Ge_{10}Se_{15}S_{35}$ thin film which have the excellent optical sensetivity using by He-Ne laser(632.8nm). The intensity of incident beam was 2.5mW and incident angle that $2{\theta}$ is $20^{\circ}$. We formed the holographic grating after had formed the 1-dimansional holographic grating and then rotate the sample. We confirmed that 2-dimensional holographic grating result of the figure of diffracted beam and AFM(Atomic Forced Microcopy) image.
